This is a fallacy the Kings sold to their fans for 44 years. The Kings in 2012 through 2014 was a team built for the playoffs, and it showed when they decided to bring their "playoff game" to regular season games at various points during a season.
They couldn't bring their old "playoff game" to any regular season games last season or this season.
Getting bounced in the 1st round on a consistent basis with an aging core isn't going to do anything to get me excited about going to games.
Sorry, but the window is closed. Dean won't be able to rid himself of the Brown and Gaborik contracts. By the time those deals are off the books Kopitar, Doughty, and Quick will all be in their early - mid 30's.
It's problematic Kopitar will regain his form for a prolonged period of time, if at all. By the time Dean can afford to get him the help he obviously needs, because he can't produce like a $10M cap hit player should, Kopitar will no longer be a 1C capable of dominating a playoff series.
